Aspirator stop valve (" ASOV ") 120 is arranged the floss hole 108a of aspirator 102 in fig 1 and 2 and many mouthfuls
Between joint 118.ASOV120 can be the gate valve with piston 121, the motion of its control brake mechanism 123, the wherein brake mechanism
Can change between the open and the closed positions.ASOV can be pneumatically actuated.In fig. 2, ASOV120 makes its gate
Structure is in the close position, and brake mechanism stops the fluid between the floss hole 108a of aspirator 102 and low pressure place 116 in the position
Flowing.ASOV120 can may be operably coupled to the computer in vehicle or controller 125 to be based on specific, pre-programmed
Systematic parameter automatically control ASOV120 in open position or closing position.Alternatively, ASOV120 can be operationally
The meter that is connected on pump orifice 124 or another part or controller in being integrally formed at system 100 or vehicle, to set up
Parameter automatically and dynamically controls ASOV120 so as to be based on the swabbing pressure measured for example at pump orifice 124 and is opening
Conversion between position and closing position.In one embodiment, ASOV120 can illustrate and be described in apply for 2014
The U.S. Patent application No.14/154 in January 14, the type in 268, it is incorporated herein entirely through reference.
In another embodiment, with reference to Fig. 3, ASOV can be Electromagnetically actuated ASOV120 ', for example, illustrate and be described in
U.S. Provisional Patent Application No.61/872, the type in 402, it is incorporated herein entirely through reference.ASOV120 ' may include
Solenoid coil 180 and the armature 182 of valve system 184 is may be connected to form spring gate assembly 186, wherein the component can be linear
ASOV is opened and/or closed in the mobile applying to pass through electric current.
ASOV can also be alternatively shown as be described in the US provisional patent that applies on December 11st, 2013
Application No.61/914, the ASOV of the electromagnetism activation in 658, it is incorporated herein entirely through reference.Alternatively, ASOV120
Can take can optionally allow for as described above ASOV and/or stop by the fluid stream of system 100 it is various its
Any one in its form.
Therefore, as illustrated in Fig. 1, the first flow path 134 is limited at high-voltage power supply 112 and low pressure place 116 via aspirator 102
Between, and second flow path 136 is limited between high-voltage power supply 112 and low pressure place 116 and passes through via aspirator 102
ASOV120 is controlled.When positions of the ASOV120 in closure, flow path 136 is blocked and aspirator 102 is for by suction
The suction of mouth 124 is not contributed.In alternative embodiments, in the case of same effect, ASOV120 can on the contrary along stream
Footpath 136 is positioned at before aspirator 102, be positioned at high-voltage power supply 112 and the import of propulsion mouth 106a between (but in many mouthfuls of joints
114 downstream).Although system disclosed herein 100 is described relative to the first and second flow path 134,136, system
The aspirator and/or ASOV of extra serial or parallel connection are not limited and may include by it.Should be in other of automotive engine system
Any flow path between part includes the first and second aspirator as described in this article 102,104 to produce and/or control
Vacuum is produced and used.
In operation, under conditions of some engine operations, based on ASOV120 be in open position or in closing position,
Aspirator 102,104 can be controlled to quickly produce vacuum and/or the depth to produce various vacuum.When ASOV120 is beating
During open position, flow path 134,136 all utilizes on one's own initiative the propulsion stream by aspirator 102,104, and both contributes to as needs
The device 126 of vacuum produces the suction by pump orifice 124.Due to allow by system 100 propulsion stream initial fork and
Subsequently the help of many mouthfuls of joints 114,118 of recombinant, freely travels logical from high-voltage power supply 112 to the propulsion stream of low pressure place 116
Cross flow path 134,136.Therefore, the Venturi effect produced in aspirator 102,104 produces suction stream 138 along flow path 134
(being illustrated with arrow in Fig. 1), and suction stream 140 (illustrating with arrow in Fig. 1) is produced along flow path 136, these suction streams are together
Cause the total suction by pump orifice 124.
On the contrary, when ASOV120 is in closing position, only flow path 134 (rather than flow path 136) produces pass through on one's own initiative
The suction of pump orifice 124.Because ASOV120 prevents to pass through flow path 136 between high-voltage power supply 112 and low pressure place 116 in closing position
Fluid communication, so without obvious pressure difference come along flow path 136 extract out fluid stream.Due to lacking the pressure on flow path 136
Poor driving force, sets up without Venturi effect in aspirator 102 and is aspirated simultaneously necessary to check-valves 128a to produce to open
And finally contribute to suction by pump orifice 124.Therefore, when ASOV120 closure position when, only aspirator 104 (and
It is not aspirator 102) with the effect for producing the suction by pump orifice 124.Additionally, because ASOV120 is not affected by stream
The flowing in footpath 134, so ASOV can not interfere the swabbing pressure that flow path 134 is produced.
According to it is disclosed herein and description principle, by control aspirator 102,104 physical flow feature and
It is used to opening and closing the operating parameter of ASOV120 by setting, inhaler system 100 can be utilized to form for vehicle
Simple, the cheap variable flow rate control device of engine.Condition for automatically opening up and closing ASOV can be according to passing through
The desired propulsion mass velocity of system and/or desired suction generation degree are programmed, thus allow system according to suitable
The demand of given system 100 dynamically respond and adjust propulsion mass velocity.Additionally, system 100 can make propulsion matter
Amount change in flow, while swabbing pressure is constantly produced by least one of multiple aspirators.
It is detailed and of the invention by referring to its preferred embodiment description, appended without departing from being limited to for the present invention
On the premise of scope in claim, it is clear that can modify and change.
